This provided a way to quantify drug use and sociodemographics and assess the accuracy of drug survey techniques. The data show the expected regional, sub-regional and temporal patterns of illicit drug use, such as more MDMA consumed on the weekends than during the week. The key take home messages is that, in combination with complementary data like censuses, surveys and seizure information, wastewater analysis can help guide harm reduction policy for the wellbeing of New Zealand. Reducing the MRI outpatient waiting list through a capacity and demand time series improvement programme Heera Bhullar, Bernadette County, Stuart Barnard, Anne Anderson, Mary E Seddon A partnership between Ko Awatea and the radiology department at Counties Manukau District Health Board aimed to match the demand for magnetic resonance imaging (MRI) with the available capacity. Using quality improvement techniques, the team successfully and sustainably reduced the MRI waiting list over a two-year period, reducing the number of patients waiting from nearly 2,000 to just over 400. The innovative solutions to segment the waiting list and match capacity to demand may be instructive for other radiology depart- ments, and other waiting list scenarios. Does research help to inform a district health board’s purpose? A qualitative thematic analysis of clinician researcher views Lorraine Neave, Duncan Reid, Brian McKenna This study explored, from a district health board (DHB) staff perspective, what the enablers and barriers to doing research were and whether the outcomes of research activity helped it deliver best care. It has provided insight into how organisational factors can negatively influence engagement in and with research and thereby impact the potential for research to inform the DHB’s overarching purpose. These factors are all modifiable influences. The themes offer a direction for the DHB’s future research strategy, where research activity is integrated into practice, where research evidence is discussed and where research achieve- ments are celebrated. The findings from this study will likely resonate across New Zealand’s DHB landscape. How common are non-acute coronary syndrome (ACS) diagnoses in patients with suspected ACS investigated with coronary angiography in New Zealand? (ANZACS-QI 58) Charles Yao-Cheng Ho, Mildred Lee, Seif El-Jack, Peter Barr, Mark Simmonds, Gerry Devlin, Philip D Adamson, Michael Williams, Andrew J Kerr Falsely activated coronary catheter laboratories for acute ST elevation heart attacks are low in New Zealand. Non-ACS conditions receiving invasive coronary angiography varies between DHBs requires more investigation.

Despite the increasing evidence around the relatively poor efficacy and increased risks associated with antipsychotic and sedative prescription in individuals with dementia, this study shows the use of these medications in dementia care and psychogeriatric facilities remains high, with 48.2% of residents in this study currently prescribed an antipsychotic and 22.1% prescribed a sedative. Furthermore, less than 20% of those prescribed an antipsychotic or a sedative had the most recent dose change occur within the 12 weeks recommended by guidelines, with over 30% of those prescribed an anti- psychotic and 48% of those prescribed a sedative not having their dose adjusted for over a year. With clear evidence of the risks of antipsychotics in dementia, the proportion of resi- dents prescribed an antipsychotic or sedative in this study, in conjunction with the prolonged duration of prescription, is cause for concern and needs addressing.
